Imaging linear and circular polarization features in leaves with complete Mueller matrix polarimetry

June 1, 2018
Author(s)
C.H. L. Patty, David Luo, Frans Snik, Freek Ariese, Wybren J. Buma, Inge L. ten Kate, Rob J. van Spanning, William Sparks, Thomas Germer, Gy?z? Garab, Michael W. Kudenov
Spectropolarimetry of intact plant leaves allows to probe the molecular architecture of vegetation photosynthesis in a non-invasive and non-destructive way and, as such, can offer a wealth of physiological information. In addition to the molecular signals

Nanoscale photocurrent mapping in perovskite solar cells

June 1, 2018
Author(s)
Yohan Yoon, Dongheon Ha, Ik Jae Park, Paul M. Haney, Sangwook Lee, Nikolai Zhitenev
In this work, we study spatially-resolved generation of photocurrent of methylammonium lead iodide (CH3NH3PbI3) perovskite solar cells to reveal the microscopic effects of annealing temperature and degradation under light exposure. Correlating a novel

Optimization of 6 LiF:ZnS(Ag) Scintillator Light Yield using GEANT4

June 1, 2018
Author(s)
Y. Yehuda-Zada, Kevin N. Pritchard, Jeffrey B. Ziegler, P. Yvonne Barnes, Kerry Siebein, M. Jackson, C. Hurlbut, Y. Kadmon, Y. Cohen, R. M. Ibberson, Charles Majkrzak, Nicholas C. Maliszewskyj, I. Orion, A. Osovizky
A new cold neutron detector has been developed at the NCNR for the CANDoR project. Geometric and performance constraints dictate that this detector be exceptionally thin (2nm). For this reason, the design of the detector consists of 6LiF:ZnS(Ag)

Investigation of Residential Cooktop Ignition Prevention Technologies

May 31, 2018
Author(s)
Sung Chan Kim, Anthony Hamins, Matthew Bundy
Several international standards and regulations regarding residential cooktop ignition prevention have existed for as long as a decade. A series of cooking experiments were conducted by National Institute of Standards and Technology (NIST) to examine the

Navigating Unmountable Media with the Digital Forensics XML File System

May 31, 2018
Author(s)
Alexander J. Nelson, Alexandra Chassanoff, Alexandra Holloway
Some computer storage is non-navigable by current general-purpose computers. This could be because of obsolete interface software, or a more specialized storage system lacking widespread support. These storage systems may contain artifacts of great

Recent Developments in Surface Science and Engineering, Thin Films, Nanoscience, Biomaterials, Plasma Science, and Vacuum Technology

Chen, B Caja, H Yi, A Boury, S Lorcy, M C. Asensio, T Gans, D O?Connell, F Reniers, A Vincze, M Anderle
Nanometer-sized structures, surfaces and sub-surface phenomena have played an enormous role in science and technological applications and represent a driving-force of current interdisciplinary science. Recent developments include the atomic-scale

Resonator Stabilization Architecture to Suppress Switching Transient Crosstalk in I-CDM

May 30, 2018
Author(s)
Malcolm S. Durkin, Joel C. Weber, William B. Doriese, Gene C. Hilton, Daniel S. Swetz, Joel N. Ullom
The ever-increasing sizes of transition-edge sensor (TES) microcalorimeter arrays motivates improved multiplexed readout with large multiplexing factors, low power dissipation, and low levels of crosstalk. Current-summed code division multiplexing (I-CDM)

Bang-bang shortcut to adiabaticity in the Dicke model as realized in a Penning trap experiment

May 29, 2018
Author(s)
J. Cohn, Arghavan Safari-Naini, R. J. Lewis-Swan, Justin G. Bohnet, M. Garttner, Kevin Gilmore, Elena Jordan, Ana Maria Rey, John Bollinger, James K. Freericks
We introduce a bang-bang shortcut to adiabaticity for the Dicke model, which we implement via a two-dimensional array of trapped ions in a Penning trap with a spin-dependent force detuned close to the center-of-mass drumhead mode. Our focus is on employing

Educational commitment and social networking: The power of informal networks

May 29, 2018
Author(s)
Justyna Zwolak, Michael P. Zwolak, Eric Brewe
Prior studies found that the lack of an engaging pedagogy and the highly competitive atmosphere in introductory science courses tend to discourage students from pursuing STEM (science, technology, engineering, and mathematics) majors. Once in a STEM field

Reduction of Short Wavelength Reflectance of Multi-wall Vertically Aligned Carbon Nanotubes Through UV Laser Irradiation

May 29, 2018
Author(s)
Michelle S. Stephens, Brian J. Simonds, Christopher S. Yung, Davis R. Conklin, David J. Livigni, Alberto R. Oliva, John H. Lehman
Multi-wall carbon nanotube coatings are used as broadband, low-reflectance absorbers for bolometric applications, blackbody radiators, and for stray light control. Irradiation of single wall carbon nanotubes with UV laser light has been shown to remove
